Which is Better, a Single-Girder or Double-Girder?

That’s a short answer – neither…and both. There really is not an overall “right choice” when it comes to gantry cranes. Each crane has its advantages and disadvantages, depending on your facility layout, lifting needs, and budget. When choosing a crane for your facility, you’ll want to dig deep with a crane design expert to choose the right crane for your needs.

Double Girder Gantry Crane Advantages

A double-girder gantry crane typically boasts:

  • Heavier load capacity – double-girder designs are typically able to lift heavier loads than single-girder cranes.
  • Higher lift heights – double-girder gantry cranes typically lift materials at significantly higher heights.
  • Greater load movement precision – the double-girder design offers increased stability and precision for controlled load movement and precise load positioning.
  • Outstanding durability – double girder cranes can be designed to work in the harshest conditions, and withstand a lot of pressure, meaning they can last a long time when properly operated and maintained.

Single-Girder Gantry Crane Advantages

The advantages of single-girder gantry cranes are in many ways the reverse of the double-girder cranes. While double-girder cranes are tough workhorses built for the heaviest loads and gruelling conditions, their single-girder cousins are more compact, even more flexible, and cost-effective.

  • Suitable for smaller spaces – a single-girder gantry crane has a more compact design, typically able to fit into smaller spaces with less overhead space.
  • Affordable – these cranes typically cost less than their double-girder counterparts, making them a little easier on the budget if you don’t need the heavier lifting capacities.
  • Easy to install – the bulk of a double-girder gantry crane can mean they take a little longer to get up and running. Single-girder cranes are typically faster to install, reducing downtime and getting up to speed quicker.
  • Easier maintenance – while double-girder cranes may be bulkier and more durable, single-girder cranes may boast lower maintenance costs, making them even more budget-friendly.
